This was possible due to the amount of insecure IoT devices around the world. While the use of IoT to launch a massive cyber attack is something new, the vulnerabilities in those devices are not. As a matter of fact, they've been there for quite a while. In 2014, ESET reported 73,000 unprotected security cameras with default passwords (2). In April 2017, IOActive found 7,000 vulnerable Linksys routers in use, although they said that it could be up to 100,000 additional routers exposed to this vulnerability (3).

The industry agreed that a user's identity is the new perimeter. This requires security controls specifically designed to authenticate and authorize individuals based on their job and need for specific data within the network. Credential theft could be just the first step to enable cybercriminals to have access to your system. Having a valid user account in the network will enable them to move laterally (pivot), and at some point find the right opportunity to escalate privilege to a domain administrator account. For this reason, applying the old concept of defense in depth is still a good strategy to protect a user's identity, as shown in the following diagram:

Although the top three in this list are old suspects and very well-known attacks in the cybersecurity community, they are still succeeding, and for this reason they are still part of the current cybersecurity challenges. The real problem with the top three is that they are usually correlated to human error. As explained before, everything may start with a phishing email that uses social engineering to lead the employee to click on a link that may download a virus, malware, or Trojan. In the last sentence, we covered all three in a single scenario.

One of the greatest challenges in this area is to identify the attacker once they are already inside the network. The traditional detection systems such as Intrusion Detection Systems (IDS) may not be sufficient to alert on suspicious activity taking place, especially when the traffic is encrypted. Many researchers already pointed out that it can take up to 229 days between the infiltration and detection (15). Reducing this gap is definitely one of the greatest challenges for cybersecurity professionals.

Crypto and ransomware are emerging and growing threats that are creating a whole new level of challenge for organizations and cybersecurity professionals. In May 2017, the world was shocked by the biggest ransomware attack in history, called Wannacry. This ransomware exploited a known Windows SMBv1 vulnerability that had a patch released in March 2017 (59 days prior to the attack) via MS17-010 (16) bulletin. The attackers used an exploit called EternalBlue that was released in April 2017, by a hacking group called Shadow Brokers. According to MalwareTech (18), this ransomware infected more than 400,000 machines across the globe, which is a gigantic number, never seen before in this type of attack. One lesson learned from this attack was that companies across the world are still failing to implement an effective vulnerability management program, which is something we will cover in more detail in Chapter 15, Vulnerability Management.

This type of scenario is called Government-sponsored cyber attacks, but some specialists prefer to be more general and call it data as a weapon, since the intent is to steal information that can be used against the hacked party. The private sector should not ignore these signs.

In the cybersecurity field, the adoption of the Red Team approach also helped organizations to keep their assets more secure. The Red Team must be composed of highly trained individuals, with different skill sets and they must be fully aware of the current threat landscape for the organization's industry. The Red Team must be aware of trends and understand how current attacks are taking place. In some circumstances and depending on the organization's requirements, members of the Red Team must have coding skills to create their own exploit and customize it to better exploit relevant vulnerabilities that could affect the organization.

This book also focuses on defense strategies to enhance the security of a system. You will also discover in-depth tools, including Azure Sentinel, to ensure there are security controls in each network layer, and how to carry out the recovery process of a compromised system.

This book provides a clear, in-depth understanding of attack/defense methods as well as patterns to recognize irregular behavior within your organization. Finally, you will learn how to analyze your network and address malware, while becoming familiar with mitigation and threat detection techniques.

You will gradually become familiar with Red Team tactics, where you will learn basic syntax for commonly used tools to perform the necessary operations. You will also learn how to apply newer Red Team techniques with powerful tools. Simultaneously, Blue Team tactics are introduced to help you defend your system from complex cyber attacks. This book provides a clear, in-depth understanding of attack/defense methods as well as patterns to recognize irregular behavior within your organization. Moreover, you will learn how to analyze your network and address malware, while becoming familiar with mitigation and threat detection techniques.

In the next section, you will learn about the defense strategies followed by the Blue Team to enhance the overall security of a system. You will also learn about an in-depth strategy to ensure that there are security controls in each network layer, and how you can carry out the recovery process of a compromised system. Finally, you will learn how to create a vulnerability management strategy and the different techniques for manual log analysis.

According to Accenture, malware attacks are the most common type of cyber attack experienced by organizations around the world. These attacks are also the most expensive. Accenture estimates that they cost businesses an average of $2.6 million apiece each year.

The only way to successfully face down this challenge is through building organizational cyber resilience. The first step of malware protection is to know your enemy. This course will explore how to prevent malware attacks by helping you to recognize them.

This cyber security training is aimed at IT professionals who want to understand how to protect their organization from cyberattacks.This might include data administrators, those working with sensitive data, or those targeting a career in cyber security.

With a threat landscape that it is in constant motion, it becomes imperative to have a strong security posture, which in reality means enhancing the protection, detection, and response. Throughout this book, you will learn about attack methods and patterns to recognize abnormal behavior within your organization with Blue Team tactics. You will also learn techniques to gather exploitation intelligence, identify risks, and demonstrate impact on Red and Blue Team strategies.

One of the greatest challenges in this area is to identify the attacker once they are already inside the network. The traditional detection systems such as intrusion detection systems (IDS) may not be enough to alert on suspicious activity taking place, especially when the traffic is encrypted. Many researchers already pointed out that it can take up to 229 days between infiltration and detection [15]. Reducing this gap is definitely one of the greatest challenges for cybersecurity professionals.

This type of scenario is called a Government-sponsored or state-sponsored cyber-attack, but some specialists prefer to be more general and call it data as a weapon, since the intent is to steal information that can be used against the hacked party.

With the increase of devices connected to Industry 4.0-enabled networks, the surface of attack also expands. Malicious actors may find in any smart device an open door to exploit new vulnerabilities and perform attacks on them or on their infrastructure, with the intent of impacting financially a company or industry [7]. When compromised, these devices can cause serious damage to material goods, such as products on a manufacturing line, or immaterial goods, such as the leakage of sensitive information or industrial secrets. Several attacks have targeted industrial facilities and their devices, from the Stuxnet [8] in 2010, to the Trojan BlackEnergy [9] in 2015 and Mirai in 2016 [10], to recent ransomware attacks, such as the WannaCry [11] in 2017 or the LockerGoga [12] in 2019, resulting in operational and financial impact for affected companies. Thus, it is relevant to constantly monitor cybersecurity risks, the impact of attacks and the state of defense mechanisms in Industry 4.0 implementations [13]. A round of efforts, such as the one described in [14], are focused on good practices and prevention to keep Industry 4.0 implementations and it systems secure, while ensuring their normal operation and maintenance. 59ce067264
